I can't see a Vermeil disciple being able to work as an O-Coordinator for Dennis Green.
Here's a quote from Rowan's first press conference:

Quote:

...when he was asked what he had learned from Kansas City coach Dick Vermeil, whom Rowen had worked under the past four seasons. Rowen choked up, and had to pause to regain his composure. “I learned that people matter,” Rowen finally said, “and what you do for one another is as important as anything you do.”

Then he asked for several moments of silence to compose himself and wipe away the tears.
